结构健康监测技术为钢筋混凝土结构的损伤预警、安全评估和维修设计提供了科学依据。研究了基于电化学原理的钢筋混凝土结构腐蚀监测系统中的关键硬件--固态限流腐蚀传感器。采用有限元法模拟了混凝土中的电场分布,优化了传感器的几何结构。仿真结果表明,优化后的腐蚀传感器可以将电场精确地限制在一个固定的区域内。
Structural health monitoring techniques provide the scientific basis for damage early-warning, safety assessment and maintenance design of reinforcing concrete structures. Solid-state and current confining corrosion sensor, the key hardware component in corrosion monitoring system based on electrochemical theory for reinforcing concrete structures, is investigated here. The finite-element method is applied to simulate the distribution of the electric field in concrete and optimize the geometric configuration of the sensor. The simulation results indicate that the electric field can be confined accurately in a fixed region by the optimized corrosion sensor.
